I am trying to add a “Caldera form” plugin on my website, but I keep getting a jquery error when loading the page:

<span style=”font-family: ‘Helvetica Neue’, Helvetica, Arial, sans-serif; font-size: 14px; background-color: #f9edbe;”>An out of date version of jQuery is loaded on the page. Form may not function properly.</span>

On the caldera forms support website, I find that it should be related to the theme:

Hello, the jquery version depends on WordPress.
For the forms, the theme is compatible with Contact Form 7 and not with the form framework you are using, please switch to that plugin instead as is also better with more possibilities and functions.
Thanks
